Half of these exist because I was bored once.
The Windows 10 and MacOS ones are GPU passthrough enabled and what I occasionally use if I have to use a Windows or Mac application. Windows 7 is also GPU enabled, but is more a nostalgia thing than anything.
I think my PopOS VM was originally installed for fun, but I used it along with my Arch Linux, Debian 12 and Testing (I run Testing on host, but I wanted a fresh environment and was too lazy to spin up a Docker or chroot), Ubuntu 23.10 and Fedora to test various software builds and bugs, as I don’t like touching normal Ubuntu unless I must.
The Windows Server 2022 one is one I recently spun up to mess with Windows Docker Containers (I have to port an app to Windows, and was looking at that for CI). That all become moot when I found out Github’s CI doesn’t support Windows Docker containers despite supporting Windows runners (The organization I’m doing it for uses Github, so I have to use it).
Well I do but I have a machine with 3/4 of a terabyte of memory on it.
Work scraps are great sometimes.
How are you running the MacOS VMs. The machine I have is a cheese grater so that makes it easier.
I found a prebuilt OpenCore for KVM. https://github.com/thenickdude/KVM-Opencore
I then changed the config.plist to make it think it was a 2019 Mac Pro.
Ok I’ll have to try this. The weird thing is my little test proxmox server is a 2013 trashcan. So this would be like a hackintosh running on Mac hardware. Would that technically be a hackintosh? I’m not really sure. According to the Apple license you can virtualize MacOS if it’s running on Mac hardware. I’m not sure if that requires MacOS as the hypervisor. Regardless this is not something I knew about. Very cool. Thanks for the info.
Are you running macOS or Linux as your host? My MacBook is M1 and I found the performance running ARM windows and ARM Fedora via UTM (qemu) to be pretty good.
On the cheesegrater(2019 MacPro) it’s a little convoluted. During covid times it was my single box lab since it had so much memory (768TB). So I was running nested ESXI hosts and then VMs under that. I also have a M1 MacBook Pro that I had parallels run ARM VMs (mostly MacOS, Windows, and a couple of Debian installs I think).
I have been looking at VMWare alternatives at work so for the hypervisors I’ve been playing around.
I do this stuff for a living but I also do it home for fun and profit. Ok not so much profit. Ok no profit but definitely for the fun. And because I love large electric bills.
That’s a beast of a Mac. Wake on lan is your friend. I have the same problem with my Threadripper. I wrote a script that issues a WOL command to either start/unsuspend my Ubuntu machine so I can turn it off when not in use. It’s probably $70/month difference for me. Most of my virtualization is on Linux but I’ve moved away from VM Ware because QEMU/KVM has worked so well for me. You should check out UTM on the Mac App Store and see if that solves any of your problems.

Man this thread has taught me all sorts of things. I will definitely check out UTM. Thanks for that!!
